How to fix the problem of a French door that won't lock
It could be a major safety risk if your doors don't latch or lock properly. This could be an indication of a major issue like a damaged locking cylinder. Don't worry, the problem is fixable with just a few steps.
Most often, doors that don't lock is because there is an obstruction blocking the latch. This can be something as simple as a small piece of dirt that has gotten stuck in the lock or it could be a problem with the latch itself.
If you look at the strike plate (the metal piece on the side of the doors that is positioned against the frame) It is possible to determine if it is true. If you notice a tiny metal stub sticking out from the strike plate gently tap it using a screwdriver to bend it. This will allow the bolt to drop in more easily.
A seized latch could be the result of improper installation or poor alignment. Lubricating the latch may help it work better, but it will not solve issues with the way it lines up with the strike plate.
Installing a strike plate is straightforward if you don't already have one. The lock body (the part that screws into the door frame) will need to be removed from the door and the lock assembly replaced. You'll need a Phillips-head screwdriver and a power drill for this, but it is not a difficult job.
It is a good idea to ensure that the lock is lubricated especially the cylinder regularly to ensure that it functions as efficiently as possible. You can use silicone or graphite oil to do this. Apply the lubricant to the key, then rotate it several times until the cylinder moves freely.
It's a good idea to invest in a double-cylinder deadbolt for your French doors, rather than simply a standard deadbolt. A simple handle twist lock isn't enough to stop intruders from entering, and a standard deadbolt with an internal thumb-turn of the door could be beaten by breaking the glass and then reaching in through it.
Fixing a French Door That Won't Latches
The issue is usually caused by the door latch not properly connecting to the strike plate hole. It is usually caused by the hinges being sagging. However, it can be caused by a problem with the latch position or the latch itself. You could use a marker, such as lipstick, or a similar marker, to determine which is the culprit. This mark will help you determine the cause of the issue. For instance If the mark is below the strike plate it's most likely to be the hinges. If it's above it could be the position of the latch.
It is crucial to ensure that the strike plate is aligned with the latch holes when installing handles or a lock mechanism on a French Door. This is particularly important in the event that one door was closed for a long amount of time. In this time, the door could be a bit shifted. This is particularly common with wooden and composite doors because they are prone to contraction or expansion based on the weather conditions or the surrounding environment.
To correct this, first take the latch from the active door's edge. Then, remove the locking strip from the handle. With a chisel that is sharp, the hammer and a chisel enlarge strike plate hole in the door frame. This will allow you to put the latch in a more ideal position for the door. When the door is closed, it will close without catching the frame.
After the hole for the latch has been enlarged, carefully insert the new latch in the strike plate hole and screw it in. Then, re-adjust the strike plate with the screw and hammer until it is in the correct position, and then test the door. Make any adjustments as required.
The lock cylinder on external French Doors won't turn. This can be due damage or wear and tear. However, it is usually a simple fix. The lock may be blocked or the pins of the cylinder are worn. It's worth trying to see if a quick clean will make a difference. If the issue persists it could be necessary to replace the lock cylinder.
How to fix a French Door that isn't opening
If your French door doesn't lock due to dirt or other debris It is likely that the mechanism is blocked. The first thing you need to do is to check that the frame of the door is free from obstructions and that there is nothing blocking the mechanism that locks. There could be an issue with the alignment of the French door and its frame. This can cause the door to drag over the frame, which can eventually lead to jamming.
The mechanism behind the lock is pretty simple - the key turns a spindle that then moves a bolt back and forth on a rail. If the handle turns but the bolt isn't moving, this means that something is stuck. It could be a problem with the mechanics of the lock itself or it could just need lubricating. Make use of a silicone spray. It will come with a nozzle you can use to direct the lubricant directly into the mechanism. Spray generously and then turn the handle until the lubricant has reached all the parts of the mechanism.
You may also have to adjust the position of the latch on the French door. It is generally possible to do this from outside. If your French doors are new they will be capable of screwing the latch and handle into place without difficulty. If your French doors are older, you'll need to use the template that comes with the lock kit to mark the location where the holes for the handle on the door and the latch on the frame must be. Make the hole for the knob or handle at the appropriate height. It is typically about 36 inches above the floor. Then, drill a smaller hole on the outside of the door to install the latch.
After drilling the hole, it's important to ensure that the latch plate is properly placed over the strike plate that is on the door frame. If the latch plate doesn't fit properly, the deadbolt will not retract into the strike plate when you push the lock lever. Finally, you will have to screw the latch plate in the correct position.
Fixing a French Door That Won't Close
Sometimes, the latch on a French door is stuck and it won't close, making the doors unusable. This is usually a simple issue to fix, but it could require removal of one of the heavy doors. The most common cause is that the latch isn't aligned or with the strike plate, or with the jamb on the door, or both. It could also be because the dead bolt isn't extended or retracted fully. Misalignment can occur as time passes due to weather conditions or the settling.
If the latch is stuck, it may be difficult to open, but it's generally easy to fix the problem by loosening the screws that secure the hinge to the frame, and then adding shims to make the door a bit higher or lower. This will allow the latch to be closer to lock mechanism and fix the problem.

In the same way, if the latch isn't able to get into position with the strike plate's hole on the door jamb it is usually possible to fix the issue by loosing a screw that holds the strike plate, and using an electric or metal planer to remove a portion of the edge of the plate until the latch fits. If necessary, you may also have to remove the strike plate to cut out the hole.
Another issue that is common to French doors is that the locks do not engage correctly. If you have a newer lock system, this could indicate an issue with the locking cylinder. It is necessary to remove the lock and examine it for obvious obstructions or damage and if it's not functioning properly, you may require replacing it.
If you have an older door that has a draught coming in, try replacing the weatherstripping that was used on the outside of the doors. This will form a tight seal and prevent the doors from sagging. You can also add door sweeps to ensure that all the gaps that could be created are sealed. If repair french doors do this, make sure that you place the sweeps on both sides of the door and that the sweeps overlap at the bottom.
